As noted in #870 curl_httppost is deprecated and therefore need to be replaced.
I replaced it with curl_mime. This change requires at least curl 7.56.0.
This requirement is no problem, since we use curl 7.80.0 internally and demand at least 7.71.0 for the use of system curl (CPR_USE_SYSTEM_CURL).
The option to enable NPN got also limited to curl [7.37, 7.85] to prevent an additional deprecation warning.
